How to Use Your Pigments

HOW TO USE YOUR PIGMENTS

For Jesmonite® AC100, AC300, AC730, and other plaster/gypsum-based eco-resins or cement (NOT for epoxy resin).

    • How much pigment should I use?
      • Extremely concentrated—15 ml can colour well over 30–40 coasters.
      • Keep to a maximum of 2% pigment by weight of total mix (e.g., 20 g pigment per 1 kg of total mix for a strong, saturated colour).
    • How do I use the pigments?
      1. Shake the bottle well (at least 30 seconds) before use so the blended colors recombine.
      2. Always mix the pigment into the liquid component (Jesmonite® or polymer liquid) first.
      3. Once thoroughly combined, add the powder component.
      4. Mix thoroughly before pouring into your mold. Insufficient mixing can result in a mottled effect.
      5. Do not add the pigment directly to the powder or mold.
      6. For marble or ombré effects, prepare smaller amounts of different shades and combine in the mold.
      7. For terrazzo effects, create different coloured “chips,” let them set, then add them to a fresh mix.
    • How do I get different shades?
      • Vary the concentration of pigment.
      • For pastel tones, start with a tiny amount (e.g., a toothpick tip).
      • For deeper colours, add pigment one drop at a time until you reach the desired shade.
      • It’s easier to start light and go darker—once a colour is too dark, you can’t lighten it without starting over.

    HOW TO SEAL YOUR PIECES

    • Protect your INTERIOR Jesmonite® or plaster/gypsum eco-resin home decor products with my “Finishing Touch 100% Natural Coconut Oil & Soy Wax Sealer”.
    • This should make your final colour slightly more vivid and add a lovely sheen.
    • It adds a splash proof protection but is NOT 100% waterproof or dishwasher safe.
    • Not for use on outdoor products or candle containers
